Concentration & Spell Durability ✨🧠


🔮 What Is Concentration?

Concentration is how spellcasters maintain ongoing magical effects over time.

  • Many buffs, control, and utility spells require it.

  • You can only concentrate on one spell at a time.

  • Losing concentration means the spell ends immediately.

Examples of concentration spells:

  • Bless (support allies)

  • Invisibility (sneak unseen)

  • Hold Person (paralyze enemies)

  • Fly (grant flight)

If you want to juggle multiple effects — tough luck! Only one concentration spell can be active per caster at any given time.


⏳ How Long Does It Last?

Each spell lists its duration (e.g., “Concentration, up to 1 minute”).
You can end concentration anytime — no action needed.

  • 1 minute = 10 rounds of combat.

  • Some last longer — up to 10 minutes, 1 hour, or even 8 hours!


⚠️ Losing Concentration

Concentration can break in several ways:

  1. Casting another concentration spell — ends the first one.

  2. Taking damage — you must make a Constitution saving throw to keep focus.

    • DC = 10 or half the damage taken (whichever is higher).
  3. Being incapacitated or killed.

  4. Environmental effects — extreme weather, shaking, or distractions (DM’s call).

Example:

  • A Wizard is concentrating on Fly.

  • They take 22 damage from an arrow.

  • They must roll a Constitution save DC 11 to keep the spell.

  • If they fail — splat! The flying ends immediately. 💥


🛡️ How to Protect Concentration

  • Stay behind cover — avoid unnecessary hits.

  • Boost Constitution (saves matter!).

  • Take the War Caster feat for advantage on concentration saves.

  • Use spells like Mirror Image or Blur to reduce incoming damage.

  • Allies can protect you using positioning or body-blocking. 🧙‍♂️🛡️


💡 Quick Tips for Spell Durability

  • Choose non-concentration spells to stack effects (e.g., Magic Missile + Shield).

  • Concentrate smartly — pick what benefits the party most.

  • If you’re hit often, consider Defensive fighting styles or spells.
